Heterogeneous Distillation of theSystem Water-Acetic Acid- p-Xylene: Study of its Fluid Phase Equilibria, Micro-Pilot Column Experimental Results and Computer Simulation

open access: yesChemical Engineering Transactions, 2013
The separation of the binary mixture water-acetic acid by direct distillation is not suitable for industrial applications because of the presence of a tangent pinch on the pure water end.

Effective lipid extraction from undewatered microalgae liquid using subcritical dimethyl ether

open access: yesBiotechnology for Biofuels, 2021
Background Recent studies of lipid extraction from microalgae have focused primarily on dewatered or dried samples, and the processes are simple with high lipid yield. Yet, the dewatering with drying step is energy intensive, which makes the energy input

Entrainer Recycle for Batch Heteroazeotropic Distillation

open access: yesChemical Engineering Transactions, 2017
The influence of entrainer (and off-cut) recycle are studied by dynamic simulation for a batch heteroazeotropic distillation (BHAD) process. For the dehydration of isopropanol, toluene is applied as entrainer (E).

Isopropyl Alcohol Purification through Extractive Distillation using Glycerol as an Entrainer: Technical Performances Simulation and Design

open access: yesJurnal Bahan Alam Terbarukan, 2019
Isopropyl alcohol is widely used as industrial chemical intermediates and common solvents in households, pharmaceuticals, food, cosmetics, and medical purposes. The high purity of isopropyl alcohol requires special separation from its impurity i.e. water

Isopropyl alcohol recovery by heteroazeotropic batch distillation [PDF]

open access: yes, 2010
Solvent recovery is becoming a major issue in the pharmaceutical and specialty chemical industries. Solvent recovery by conventional batch distillation is limited by the frequent presence of azeotropes in the used solvent mixtures.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

Observational constraints on entrainment and the entrainment interface layer in stratocumulus [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Abstract. Aircraft sampling of the stratocumulus-topped boundary layer (STBL) during the Physics of Stratocumulus Top (POST) experiment was primarily achieved using sawtooth flight patterns, during which the atmospheric layer 100 m above and below cloud top was sampled at a frequency of once every 2 min.

From batch to continuous extractive distillation using thermodynamic insight: class 1.0-2 case B [PDF]

open access: yes, 2011
A systematic feasibility analysis is presented for the separation azeotropic mixtures by batch and continuous extractive distillation. Based on batch feasibility knowledge, batch and continuous separation feasibility is studied under reflux ratio and ...

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

open access: yesAdvanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...
